Patent number: 5846051Abstract: A sealing device for dust- and liquid-aspirating machines, comprising an electric motor provided with a shaft, to a cantilevered free end whereof an axial suction impeller is fixed, the impeller being contained in a casing wherein one or more delivery ducts are formed peripherally. The device further comprises an axially perforated disk-shaped element associated with the shaft, interposed between the motor and the casing, and having a perimetric surface shaped so as to form at least two successive tapering regions between which a change in diameter is interposed and forms a step, the configuration of the disk-shaped element being adapted to repel the liquid by centrifugal action and to dissipate its energy in association with the facing surface of a flanged sealing element having a hollow section that encapsulates part of the electric motor, and a flange connected to the casing upon assembly.Type: GrantFiled: May 12, 1997Date of Patent: December 8, 1998Assignee: Rotafil S.a.s.
